Hi. My name is Katerina. But I prefer Kate. It's a little more this 'time'. I was named after my grandmother. You may know her. Her name is Katerina Petrova. But I think she goes by Katherine Peirce now. You see my mother, Isobel, she gave birth to twins that day. But only gave one to the Gilbert family. Keeping me for herself for about five years. Eventually giving me up so she could shut her emotions off. But now I'm back to search for the answers to my questions. Elena Gilbert. My indentical twin sister. Only problem? Nobody can know I exist.. After all I am the only vampire hunter that is always 1 step ahead of Niklaus.
